The invention provides an early warning method of cardiovascular and cerebrovascular events caused by space disastrous weather. The method comprises the steps that on the basis of the space disastrous weather stage caused by solar activities, 2-3 days of early warning time can be obtained by using low frequency solar radio burst observation data, wherein the method for conducting a drug intervention on the cardiovascular and cerebrovascular events during this period comprises a high risk group grouping method, the step of drug aid therapy in the three days of early warning, the step of drug therapeutic effect judgment and the like. Due to the fact that cardiovascular and cerebrovascular disease drug interference experiments are conducted within the early warning time, the cardiovascular and cerebrovascular events of high risk groups caused by the disastrous space weather can be well prevented. The early warning method of the cardiovascular and cerebrovascular events caused by the space disastrous weather has the advantages of being scientific, good in operability and the like.
